Caption: Beamline 19 at the European Synchrotron Radiation Facility (ESRF), Grenoble, France. The ESRF produces high energy radiation in the form of X-rays. Electrons, produced by an electron gun, are accelerated in linear and circular accelerators. The high energy electrons are then transported within an 844 metre circumference storage ring, before being directed to beamlines. An optics cabin at each beamline allows researchers to tailor the X-rays for use in a variety of experiments. At the time of its inauguration on September 30, 1994, the ESRF was the world's brightest source of X-rays. It can produce X-rays that are one thousand billion times brighter than hospital X-rays.
